Abstrak Budidaya udang windu (Penaeus monodon) menghadapi ancaman serius akibat infeksi bakteri Vibrio sp., yang dapat menyebabkan vibriosis dan Acute Hepatopancreatic Necrosis Disease (AHPND) dengan tingkat mortalitas lebih dari 90%. Penggunaan antibiotik sintetis yang tidak terkontrol dapat memicu resistensi bakteri dan meninggalkan residu berbahaya pada produk perikanan, sehingga diperlukan alternatif antibakteri yang efektif dan ramah lingkungan. Penelitian ini bertujuan mengevaluasi efektivitas kalsium oksida (CaO) yang disintesis dari limbah cangkang kerang kapah (Meretrix sp.) sebagai agen antibakteri terhadap Vibrio sp. CaO diperoleh melalui kalsinasi tepung cangkang pada suhu 1000°C dan dikarakterisasi menggunakan spektroskopi FTIR. Pengujian aktivitas antibakteri dilakukan dengan metode difusi cakram menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan yaitu kontrol positif amoksisilin, kontrol negatif etanol, CaO 5%, 10%, dan 15%, masing-masing tiga ulangan. Hasil karakterisasi FTIR mengkonfirmasi terbentuknya CaO yang ditandai munculnya puncak vibrasi ikatan Ca–O pada bilangan gelombang 551,64 cm⁻¹ dan 397,34 cm⁻¹. Hasil pengujian menunjukkan bahwa seluruh konsentrasi CaO mampu menghambat pertumbuhan Vibrio sp., dengan diameter zona hambat tertinggi pada konsentrasi 15% sebesar rata-rata 5,67 mm.Uji One Way ANOVA menunjukkan perbedaan signifikan antar perlakuan (p = 0,006; p 0,05), mengindikasikan bahwa aktivitas antibakteri CaO bersifat semakin tinggi konsentrasi, semakin kuat efeknya. Mekanisme kerja antibakteri melalui, pembentukan Reactive Oxygen Species (ROS), denaturasi protein, dan kerusakan membran sel bakteri. Penelitian ini menyimpulkan bahwa CaO dari cangkang kerang kapah berpotensi dikembangkan sebagai agen antibakteri alami dan ramah lingkungan untuk mendukung budidaya udang yang berkelanjutan. Kata kunci: Akuakultur; Difusi cakram; Meretrix sp.; Vibrio sp.; Zona hambat. Abstract Tiger prawn (Penaeus monodon) aquaculture faces a serious threat from Vibrio sp. bacterial infections, which can cause vibriosis and Acute Hepatopancreatic Necrosis Disease (AHPND), with a mortality rate exceeding 90%. The uncontrolled use of synthetic antibiotics can trigger bacterial resistance and leave harmful residues in fishery products, necessitating the development of effective and environmentally friendly antibacterial alternatives. This study aims to evaluate the effectiveness of calcium oxide (CaO) synthesized from waste shells of the kapah clam (Meretrix sp.) as an antibacterial agent against Vibrio sp. CaO was obtained through calcination of shell powder at 1000°C and characterized using Fourier Transform Infrared (FTIR) spectroscopy. Antibacterial activity testing was conducted using the disc diffusion method with a Completely Randomized Design (CRD), comprising five treatments: a positive control of amoxicillin, a negative control of ethanol, and CaO at concentrations of 5%, 10%, and 15%, each replicated three times. FTIR characterization confirmed the formation of CaO, indicated by the appearance of Ca-O bond vibration peaks at wavenumbers of 551.64 cm¹ and 397.34 cm. The results show that all CaO concentrations were capable of inhibiting the growth of Vibrio sp., with the highest inhibition zone diameter recorded at the 15% concentration, yielding a mean of 5.67 mm. One-Way ANOVA revealed significant differences among treatments (p=0.006; p 0.05), indicating a concentration-dependent antibacterial activity, whereby higher concentrations produced stronger inhibitory effects. The antibacterial mechanism operates through the formation of Reactive Oxygen Species (ROS), protein denaturation, and bacterial cell membrane damage. This study concludes that CaO derived from kapah clam shells has potential for development as a natural and environmentally friendly antibacterial agent to support sustainable prawn aquaculture. Keywords: Aquaculture, Disc Diffusion, Meretrix sp., Vibeto sp., Inhibition Zone.

Palm oil is one of Indonesia's principal agricultural commodities and a key driver of agribusiness development across the value chain, from production to processing. Enhancing palm oil production necessitates systematic attention to multiple production factors, particularly within Tulin Onsoi District. This study identifies internal and external factors influencing production and formulates strategies to improve outcomes for the Tunas Harapan Farmer Group. The research was conducted in Tulin Onsoi District with the Tunas Harapan Farmer Group in Desa Makmur. The sample consisted of 14 farmer group members selected through purposive sampling. Data were analyzed using SWOT analysis. The findings identified several internal factors. Strengths comprised high-quality palm fruit, stable harvest volumes across growth phases, sufficient labor availability, government support, and extensive farmland. Weaknesses included limited farmer group activity, suboptimal land conditions, inadequate fertilizer supply, restricted farm capital, and distance from water sources. External opportunities included optimizing harvest potential for increased productivity, institutional support for superior seedling distribution, opportunities for technology adoption in mechanized agriculture, maximizing production output, and access to multiple fresh fruit bunch marketing outlets. Threats consisted of stricter government land regulations, restrictions on subsidized fertilizer allocation, unpredictable weather, rising pesticide prices, and palm oil price volatility. The analysis recommends defensive strategies from quadrant four, specifically eliminating intermediaries by selling directly to palm oil mills, utilizing organic waste for fertilizer production, implementing integrated pest management with natural materials, and collectively substituting organic inputs to reduce production costs.

Penelitian ini bertujuan untuk menganalisis tingkat keberlanjutan aset penghidupan petani hortikultura sayuran di Pulau Bunyu, Kabupaten This study aims to analyze the sustainability level of livelihood assets among vegetable horticulture farmers on Bunyu Island, Bulungan Regency, North Kalimantan. The assets assessed include social, infrastructure, financial, economic, and natural capital. A quantitative approach was employed using the Multi-Dimensional Scaling (MDS) technique with the Rapfish software tool. Data were collected through observation, interviews, questionnaires, and documentation from 45 purposively selected respondents. The analysis results indicate that three assets—social (68.24), economic (56.35), and natural (57.33)—fall within the moderately sustainable category. Infrastructure assets (46.53) are categorized as less sustainable, while financial assets (17.27) are deemed unsustainable. The most sensitive attributes influencing sustainability include social participation, storage facilities, water access, agricultural insurance ownership, input prices, and the impacts of climate change. These findings highlight the need for improvements in financial and infrastructure aspects through enhanced funding support and strengthened agricultural facilities, while also maintaining and further developing the performance of assets that are already moderately sustainable.

Vegetable farming in the District of East Tarakan used a polyculture cropping pattern, which is an agricultural business that cultivates various types of crops on
the same land. By planting more than one type of plant in one field at the same time in one place, there may be differences in the use of inputs which will affect
production. This research was conducted in the District of East Tarakan. The purpose of this study, was first, to determine the factors that influence the
production of vegetable horticultural food crops, secondly to analyze the factors that influence the overall production of vegetable farming, and thirdly to analyze
the partial production factors that most influence the production of vegetable farming. The sampling method was purposive sampling by quota, with a total of 30
farmers as samples. The analysis used is multiple linear regression in logarithmic form with Cobb Douglas production function. Based on the results of the F test
simultaneously, the use of land area production factors, seeds, fungicides, insecticides, shrimp shell fertilizers, chicken manure, and labor from mustard
greens, pakcoy, kale, spinach, and celery gave a very real effect. Based on the value of the determinant coefficient R2 for the five varieties, it was found that these variables can affect the production of mustard kumala by 93%, pakcoy by 86.7%, kale by 88.5%, spinach by 77.7%, and celery by 92.9%. In mustard greens, the independent variables that have a very significant effect are seeds (X2), shrimp shell fertilizer (X5), pakcoy vegetables are land area (X1), insecticides (X4), shrimp shell fertilizers (X5), kale is a land area (X1), shrimp shell fertilizer (X5), spinach is a
